Note that the Canary client is generally unsupported and should only be used if Fluxer staff specifically ask you to test something. That being said, there currently is a channel in Fluxer HQ with a list of bugs/feedback that staff are looking for and any related issues should be supported in the #canary-bug-reports channel in Fluxer HQ.
